Set Max Date (Date Picker)

Question

I want to add a upper limit to my date picker (spinner). The max date should be "today". I tried to add this line of code but then my app crashes:

dpDate.setMaxDate(new Date().getTime());

Here's the whole code, can anybody see what's wrong? :)

 addToCal.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {

            final AlertDialog.Builder mBuilder = new AlertDialog.Builder(Activity4.this);
            View mView = getLayoutInflater().inflate(R.layout.dialog_add_call,null);



            final DatePicker dpDate = (DatePicker)findViewById(R.id.dpDate);
            dpDate.setMaxDate(new Date().getTime()); //this makes the app crash



            mBuilder.setView(mView);
            final AlertDialog dialog = mBuilder.create();


            dialog.show();

        }
    });

Try this : `dpDate.getDatePicker().setMaxDate(new Date().getTime());` — Vinay Hegde, Jul 27 '19 at 16:16
I got "cannot resolve method "getDatePicker()', maybe only works for DatePickerDialog? — Daniel Andersson, Jul 27 '19 at 16:18
can you add the logs what you are getting after app crashes ? — Vinay Hegde, Jul 27 '19 at 16:20

You must add setMaxDate on onCreateDialog method like below

    @Override
    public Dialog onCreateDialog(@Nullable Bundle savedInstanceState) {

        DatePickerDialog dialog = new DatePickerDialog(getActivity(), R.style.DialogTheme,null,year,month,day);

        //set max date
        dialog.getDatePicker().setMaxDate(new Date().getTime());
    }

Okay I am not using DatePickerDialog, only a DatePicker, inside a custom Alert Dialog but thanks will try to apply what you wrote – Daniel Andersson Jul 27 '19 at 16:49
why do you do that? why do you not use DatePickerDialog and and customize it ? – Rejsi.Perpalaj Jul 27 '19 at 18:29
That's maybe a better way to do it! :D – Daniel Andersson Jul 27 '19 at 21:42
